BAIL-FASTENING.

Specification of Letters Patent.

Patented Feb. 4,1913,

Application filed March 13, 1912. Serial No. 683,453.

To all whom it may concern:

Be it known that I, TURNEY E. BUCK, a citizen of the United States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented a new and useful Bail-Fastening, of which the following is a specification.

This invention relates to means for securing the rails of rail-road tracks to the ties or other supporting structure.

The purposes of the invention are to provide a rail-fastening adapted to detachably connect the rail with its support and adapted to prevent overturning or spreading of the rails and to provide a fastening so constructed and arranged that the rail-securing device will have a firm bearing on the rail and the rail may be detachable from its support without disturbing the connecting devices connecting the rail with the ties or other-support.

The invention is illustrated in the anneXed drawing to which reference is hereby made and is hereinafter particularly described and the novel features thereof are recited in theappended claims.

The drawing is a combined elevation and sectional view of the rail-fastening.

The rail 1 is of usual construction and need not be particularly described. The chair 2 is' a metal plate of suit-able dimensions. The chair has a central flat depression 3 having vertical side walls 4. 'The chair also has transverse tapered holes 5, inclinedupper surfaces 6, and upwardly extending ledges 7. There are two metal clamping plates 8 of suitable dimensions, one on each side of the rail. The clamping plates have inclined lower surfaces 9 conforming to the inclined upper surfaces 6 of the chair, holes 10 accommodating the connecting bolts, and wings 12 having lower surfaces 12 conforming to the upper surface of the flange of the rail and adapted to bear evenly upon the flange of the rail to prevent displacement of the rail. Bolts 13 securely connect the parts together. Each bolt 13 has a polygonal part 14, an upper screw-threaded part 15, a tapered shoulder 16, and a lower screw-threaded part 17. The part 17 screws into the tie or other supporting structure. The tapered shoulder 16 .bcars firmly on the tapered wall of the hole 10.

To assemble the parts, the chair 2 will be properly positioned on the tie or other support, with the holes 5 in registry with suitable holes in the tie or other support to receive the bolts. The rail will be placed on the chair with the base ofthe rail in the depression 3 and theedges of the flanges of the rail in contact with the vertical walls 4 respectively. The bolts 13 will be inserted in the holes 10 and a suitable wrench fitting on the polygonal parts 14 will be used to screw the bolts down into the tie or other support and cause the shoulders 16 to bear firmly on the tapered walls of the holes 10 to hold the chairv securely so that it cannot move either vertically or horizontally. The clamping plates 8 will be placed on the bolts and when the plates are in place, the inclined lower surfaces of the plates will rest on the inclined upper surfaces of the chair, the outer edges of the plates will abut against the ledges 7 and the lower surfaces of the wings-12 will be in close contact with the upper surfaces of the flanges of the rail and the nuts 18 will be placed on the screwthreaded parts 15 and screwed down tightly on top of the plates 8.

When the parts are assembled as described, the shoulders 16 of the bolts will prevent lifting of the chair, or horizontal movement of the chair; the walls 4; will prevent lateral movement of the rail on the chair, the wings 12 will prevent raising or tipping of the rail and the edges of the plates 8 bearing against the ledges .7 will prevent lateral sliding of the plates, thereby obviating the danger of shearing the bolts.

- If it be removed and the rail may then be lifted off the chair without disturbing the connection of the bolts with the tie or other structure. Having fully described my invention what Iclaim as new and desire to secure by Letters Patent is:

1. In a rail-fastening, the combination of a chair having shoulders, tapered holes adapted to receive shouldered bolts, a depression adapted to accommodate the base of a rail, and walls adapted to prevent lateral movement of the rail; in combination with bolts having tapered shoulders bearing on the tapered walls of the holes in the chair and having upwardly extending screwthreaded parts; clamping plates surrounding the bolts and abut-ting against the ledges on the chair, and having wings fitting over the flanges of the rails; and nuts screwing onto said bolts to secure the plates on the chair.

2. In a railfastening, the combination of a bolt having a polygonal part, an upper screw-threaded part adapted to receive a nut, another screw-threaded art adapted to screw into a tie, and a shoulc er intermediate of the screw threaded parts; in combination with a chair adapted to support a rail and having tapered holes adapted to accommodate the shoulder of the bolt, a plate surrounding the bolt and adapted to contact with the upper-surface of the flange of a rail and a nutfitting on the upper screvw threaded part of the bolt.

3. The combination of a chair having ledges, holes adapted to accommodate tapered bolts, a depression adapted to accommodate the base of a rail, and Walls adjacent the depression and adapted to prevent lateral movement of the rail; a rail having a base fitting in the depression of the chair and flanges engaging the vertical walls of said depression; shouldered bolts connectible With a tie or other support and having screw-threaded upper parts; clamping plates surrounding the bolts and abutting against the ledges of the chair and having Wings conforming to the upper surface of the flanges of the rail; and nuts screwing onto said bolts.

In Witness whereof, I have hereunto signed my name at Springfield, Illinois, this 11th day of March, 1912.

TURNEY E. BUCK.
